I was seeing some problems with this drive when it was hooked onto the same SCSI chain as my hard drives, actually, I saw problems when it was hooked up to the same Qlogic card. I was getting I/O errors when trying to write to and erase tapes. I was using 'mt' at first, then I installed flexbackup from ports. Flexbackup uses 'mt' commands, so that did not work for me as well. So, I installed a SymBios PCI SCSI card into my machine and hung the tape drive off of it, by itself. I ran through the same procedures as above, I used 'mt' to rewind and erase tapes, rather 'mt' attempted to erase the tapes, I still got I/O errors. Flexbackup, again, was the same story. So, I read up on the 'dump' and 'restore' utilities and decided to try those out. I did a 'dump' of my /home folder and it said that it successfully dumped to tape! Interesting, so I tried to use 'restore' to see if 'dump' did what it said it did. So, I see that I have my /home folder on the tape, I select a couple files to extract the from tape, again, it worked! I am just happy that I can back up my system at this point. So, just to confirm, I ran 'mt -f /dev/sa0 erase' and I received a I/O error. Unless I am doing something wrong, it seems to me that 'mt' may have an issue. Be it either that it is broken, or it doesn't like my tape drive and dump does. I do have a TZ89 DLT drive that I can try as well, if anyone thinks that is needed.
